Answer Box: Getting Photrexa Covered by Humana in North Carolina

Humana requires prior authorization for Photrexa (riboflavin ophthalmic solution) used with iLink® corneal cross-linking in North Carolina. Success requires: (1) documenting progressive keratoconus with serial topography showing Kmax increase ≥1.0 diopter over 6+ months, (2) confirming your ophthalmologist and facility are in-network and FDA-certified, and (3) submitting comprehensive clinical records. If denied, North Carolina residents with commercial Humana plans can appeal through Smart NC external review, while Medicare Advantage members must use Humana's internal appeals process. Start today: Call your ophthalmologist to request serial corneal topography and pachymetry records from the past 12 months.

Understanding Photrexa Coverage Requirements

Photrexa (riboflavin ophthalmic solution) is used with the iLink® system for epithelium-off corneal collagen cross-linking to treat progressive keratoconus and corneal ectasia. Humana's medical policy requires prior authorization and strict clinical documentation.

Coverage at a Glance

Requirement What It Means Where to Find It Documentation Needed
Prior Authorization Mandatory approval before procedure Humana Provider Portal PA request form, clinical notes
Progressive Disease Documented worsening over time Serial corneal topography Kmax increase ≥1.0D in 6-12 months
FDA-Approved Protocol iLink® epithelium-off only Provider certification Facility must be iLink®-certified
In-Network Provider Contracted ophthalmologist Humana Provider Directory Verify before scheduling
Minimum Corneal Thickness ≥400 μm for safety Pachymetry testing Recent measurements required

Pre-Authorization Preparation

Success starts with thorough documentation. Your ophthalmologist needs to demonstrate that your keratoconus is progressing and that cross-linking is medically necessary.

Essential Clinical Documentation

Progressive Keratoconus Evidence:

  • Serial corneal topography showing Kmax increase of ≥1.0 diopter over 6-12 months
  • Pachymetry demonstrating corneal thickness ≥400 μm
  • Best-corrected visual acuity measurements
  • Documentation of failed conservative treatments (rigid contact lenses, specialty contacts)

Medical Necessity Letter Components:

  • Primary diagnosis with ICD-10 code (H18.601-H18.609 for keratoconus)
  • Objective progression measurements with dates
  • Failed treatment history with specific outcomes
  • Clinical rationale for cross-linking
  • Reference to FDA approval for iLink® system

  • Reference FDA approval and safety data
From Our Advocates

In our experience helping patients appeal corneal cross-linking denials, cases with the strongest documentation of disease progression—specifically showing Kmax increases over time with exact measurements and dates—have the highest success rates. One common mistake is submitting only the most recent topography instead of serial measurements that clearly demonstrate worsening.

FAQ

How long does Humana prior authorization take for Photrexa in North Carolina? Standard review takes up to 15 business days. Expedited review (for urgent cases) takes 72 hours. Submit complete documentation initially to avoid delays.

What if Photrexa is not on Humana's formulary? Photrexa is a medical device drug used in procedures, not a prescription medication. Coverage falls under medical benefits, not pharmacy benefits, so formulary status typically doesn't apply.

Can I request an expedited appeal if my keratoconus is worsening rapidly? Yes. Document rapid progression, corneal thinning, or risk of perforation to qualify for expedited review. Include recent pachymetry showing decreased thickness.

Does step therapy apply to corneal cross-linking? Humana may require documentation of failed conservative treatments (glasses, contact lenses) before approving cross-linking, but formal step therapy protocols are uncommon for surgical procedures.

What happens if my appeal is denied by Smart NC? For commercial plans, Smart NC's decision is final and binding. For Medicare Advantage, continue through the federal appeals process to the Administrative Law Judge level.

How do I find an in-network ophthalmologist certified for iLink® procedures? Use Humana's provider directory to find in-network ophthalmologists, then contact their offices to verify iLink® certification. You can also check Glaukos's provider locator (verify current availability).
